A particle is projected from a smooth horizontal surface with velocity v at an angle 𝜃 from horizontal . Coefficient of restitution between the surface and ball is e . The distance of the point where ball strikes the surface second time from the point of projection is . (〖v^2 𝑣𝑠𝑖𝑛2𝜃〗⁡〖(1+〗 e^2))/𝑔 (〖v^2 𝑣𝑠𝑖𝑛2𝜃〗⁡〖(1+〗 e^4))/𝑔 (〖v^2 𝑣𝑠𝑖𝑛2𝜃〗⁡〖(1+〗 e^3))/𝑔 (〖v^2 𝑣𝑠𝑖𝑛2𝜃〗⁡〖(1+〗 𝑒))/𝑔

A ball of mass m approaches a moving wall of infinite mass with a speed v along the normal to the wall. The speed of the wall is u towards the ball . The speed of the ball are after elastic collision with wall is U + v away from the wall 2u + v away from the wall |𝑢−𝑣 | away from the wall |𝑣−2𝑢 | away from the wall

A boy hits a baseball with a bat and imparts an impulse J to the ball . The boy hits the ball again with the same force , except that ball and bat are in contact for twice the amount of time as in the first hit . The new impulse equals : Half the original impulse The original impulse Twice the original impulse Four times the original impulse
